Product profile: DB9 Connector Red LED: IP Address Blue LED: TX/RX 5V Out (Pin 9) Reset / WPS DCE/DTE Mini USB Power S/W External Battery Antenna 3. Power input: 3.1 Mini USB: The USB cable is included in the package 3.2 DB9 Pin 9: 5VDC input, please select power S/W to Power in side. 3.3 External battery Standard A, AA or AAA battery: 3 units for each model. 4. Power output: Li-Polymer Battery: 3~3.7 VDC. The capacity depends on the applications. General working power consumption: 100 mah (for reference) The Pin 9 of DB9 will output 5VDC with 1 A Max. to external devices. Please slide the DIP switch to 5V Out direction on the top hole before use the function. 1

(Pressed with a clip or pin into the hole) 6. DCE/DTE Slide Switch DCE: data communication Equipment, EX: Modem DTE: data terminal equipment Use the slide switch to swap the TX and RX direction. By default, the DCE side which towards the DB9 connector side. 7.

3 9. Command set 9.1 Data mode & Command mode Launch commad mode Run Tera Term Open the assigned COM port Serial port settings: 9600 baud, 8 bits, No Parity, 1 stop bit Type $$$ Module will respond with <CMD> NOTE: The escape sequence is $$$ ONLY. There is no carriage return or line feed after the third dollar sign. Once in command mode, all commands terminate with a carriage return. 9.2 Configuration setting Changes are persistent and are reloaded after power cycling Changes are kept using the SAVE command Many settings require a reboot to take effect. 9.3 Command rules Case sensitive Spaces cannot be used, a $ is a substitute. e.g. MY NETWORK = MY$NETWORK 9.4 Shorthand's can be used set uart baudrate (valid) set uart b (valid) set u b (valid) s uart baudrate (NOT valid) 9.5 Command type (The details are listed on the document of command set) Set: Immediate effect, permanent if saved to config file Set Command AdHoc Broadcast COMM DNS FTP IP Option Sys Time UART WLAN Function controls the adhoc parameters controls the broadcast hello/heartbeat UDP message communication and data transfer, matching characters DNS host and domain FTP host address and login information IP settings optional and not frequently used parameters system settings such as sleep and wake timers Real time clock settings serial port settings such as baudrate and parity wireless interface, such as SSID, chan, and security options Get: Retrieve and display the permanently stored information Status: Current status of interface, IP address, etc. 3

4 Action: Perform actions such as scan, connect, disconnect File: Upgrade, load and save configuration, delete files, etc. 9.6 Networking Search for networks Enter command mode ($$$) scan Join a network join # 1 (remember the spaces) leave (disconnects the module from the currently associated Access Point) join <SSID string> leave Remark: If the Network is secure you must set the pass phrase first with the set wlan pass <string> command before trying to join the network Auto join a network with persistent configurations set wlan ssid <string> set wlan pass <string> save 4

5 reboot 9.7 COM Port Setting set uart baud <rate> set the UART baud rate. Valid settings are {2400, 4800, 9600, 19200, 38400, 57600, , , , }. Example: set u b 9600 sets the baud rate to 9600 baud.. set uart flow <0,1> sets the flow control mode. Default=0=Disabled, 1= hardware RTS/CTS. NOTE: Once flow control is enabled, it is important to properly drive the CTS pin (active LOW enabled) If CTS is HIGH, data will NOT be sent out the UART, and further configuration in command mode will be problematic as no response will be received. 10. WPS: Wi-Fi Protected Setup, WPS is a standard for easy and secure establishment of a wireless network via WiFi. The most common mode of WPS is the Push Button Mode (PBC) in which the user simply pushes a button on both the AP and the wireless client, the RS-232 adapter Before you use the function, please check the version will be version 2.28 and later by ls command Firmware upgrade: The following instructions detail the process of upgrading the module to version 2.28 and installing the WPS app. Send the command ftp u wifly7-227.img Send the command reboot Send the command factory R to reset to factory defaults Associate the module to the network Send the command ftp r wps7.img 10.3 Launching WPS App: Once the module is updated to version 2.28 (or later) and the WPS App is installed, there are two modes of invoking the WPS function: From the console, use the wps command Push the WPS button on the top of the RS-232 adapter by the clip Scan format updated to show AP that support WPS: In the above diagram, the APs that support WPS are listed with WPSPB in the security suites. When the WPS button is pushed on an AP, it will show up as A shown below. 5

6 11. Reset to default: Restoring Default configuration settings: 11.1 From command interface use the factory RESET command to restore the defaults. This command automatically loads default settings, and executes a save command. You then need to issue the reboot command so that the module reboots with the default configurations From hardware, press the Reset button and toggle 5 times by clip or pin on the top of the adapter. Reset is sampled at about 1 Hz, please make sure that transitions (H to L or L to H) are at least 1 second long. 12.
